Deathchase: UFO is a lo-fi remake of classic ZX Spectrum game 3D Deathchase by Mervyn Estcourt. It was made for the Four Colour Mini Competition held by Retro Remakes, which required games to use 160x100 pixels display with only 4 shades of gray similar to TI calculators.

Chase down and destroy evil alien saucers throughout the 8 sectors. Avoid crashing into trees. Aliens can be shot only in close proximity. When they are in range an indicator in bottom right of the screen will start to flash.

There are 4 saucers in each sector although you can expect more on the later stages. Special bonus is awarded for clearing all of the 8 sectors.
